You need the Xigmatek ACK-I5361 mounting hardware. It adds support for socket 1155/1156. Unfortunately, it is currently out of stock at Newegg.

If you do get it, please only use a bit of the adhesive, if at all. It is very tough to remove the backplate once the adhesive is on.

Edit: The newer revisions of the Xigmatek Dark Knight include this mounting hardware. The mounting holes for 1155 and 1156 are the same, so if you have the 1156 mounting hardware you are okay.Edited by Riou - 5/19/11 at 10:07pm

Thanks for the info, Riou.. As I just found out, it is very hard to remove the Mylex or w/e it's called adhesive from the back. I just uninstalled it from my 775. Haha. I had to use those tiny flatheads to jack it up on all 4 corners, then it popped right off. lol.

But yeah, I'm gonna go downstairs now and see if the top of the heatsink will fit where the holes are? Just to be sure..

And I'll check Micro Center tomorrow for that mounting kit.

EDIT: For 15 bucks more I COULD just get a CM 212+ .... haha.. ehh... decisions.. =/Edited by WuLF - 5/19/11 at 9:50pm

The MC website states they have 3 available at the store near me. However, they're priced at 15 dollars.. =/

Should I just upgrade to the CM 212+? I hear its an amazing cooler..

Also, are there any Different fans that I could use in the place of the stock one that comes with the CM 212? I would LOVE LOVE one with Blue LEDs!

Hey WulF! Good to see you finally pulled the trigger on Sandy Bridge!
Considering the mounting hardware is $15, I would definitely suggest picking up a CM 212+ and selling your Dark Knight. The CM 212+ is fantastic, but make sure you have a second set of hands when you go to install it, as it can sometimes be a pain to mount.
Also, you're in luck because the exact same fans that come on the CM212+ are available with blue LEDs here! Grab two of those for push/pull and you'll be good to go!Edited by VanillaCena - 5/19/11 at 10:29pm

Yeah, I have the LGA775 mounting bracket and mine's stuck on the motherboard. That's fine by me, but something to be aware of. I wonder if a hair dryer would work? I already took one to the board (along with nail polish) when I removed the Northbridge (if you're wondering by, after the board has been used, the stuff used on it is strong enough to rip the Northbridge right off the board if not heated, and the nail polish was for removing the stuff [and in the end, I didn't eve drop my temperatures, but I digress]).

Also, HEY VanillaCena! =] haha I'm also glad I pulled the trigger to get SB as well! However my Girlfriend would love to disagree. haha. Might go with the 212. I think it's on sale at MC for 25

Just watched the CM212 video on newegg.. that is SO sweet you can mount just about any 120mm fan to the Heatsink..

You're right c00lkatz, I should be going with the cheapest solution. But the 212 is a very attractive solution! Also, are there any guides on how to apply TIM to the 212? I'll do a forum search quick. Also, should you apply TIM to the HS AND the CPU itself? Or is that overkill?Edited by WuLF - 5/19/11 at 10:31pm
